Publication number: 20230228603Abstract: A clamp-on ultrasonic flowmeter includes pairs of ultrasonic transducers arranged on an exterior of a pipeline, and an electronic measuring/operating circuit for operating the transducers and for registering and evaluating measurement signals and for providing measured values of volume flow or flow velocity. The pairs are implemented as 1-traverse or 2-traverse pairs. One-traverse pairs are arranged on opposite sides of the pipeline, and 2-traverse pairs are arranged on a same side of the pipeline. At least three pairs are arranged on the pipeline and are distributed peripherally. Adjoining pairs of a number of pairs have an inner angle down to a minimum inner angle (MIA) between one another measured about a pipeline axis, which minimum inner angle obeys the following relationship: MIA=360°/(T*N*F(T,N)) with T as number of traverses and F(T,N)=0.38+0.62*T+(0.048?0.01*T{circumflex over (?)}2)*(N?2){circumflex over (?)}2.Type: ApplicationFiled: June 16, 2021Publication date: July 20, 2023Inventors: Oliver Berberig, Thomas Fröhlich, Beat Kissling, Quirin Müller, Klaus Bussinger

Publication number: 20130264142Abstract: A coupling element of an ultrasonic transducer suitable for mode conversion of an acoustic longitudinal wave between an in-coupling surface and an out-coupling surface of the coupling element. The coupling element has a first and second interface with a predetermined medium. A first angle between the in-coupling surface and the first interface and a second angle between the first interface and the out-coupling surface are so selected that a transverse waves fraction is reflected on the first interface to the out-coupling surface. The first angle between the in-coupling surface and the first interface and a third angle between the first interface and the second interface are so selected that a longitudinal wave fraction is reflected on the first interface for second interface. A fraction of the longitudinal waves reflected to the second interface is reflected on the second interface back into the coupling element.Type: ApplicationFiled: November 23, 2011Publication date: October 10, 2013Applicant: ENDRESS & HAUSER FLOWTEC AGInventors: Beat Kissling, Quirin Muller
